How to save everything displayed in cmd windows

To save everything in cmd windows as a txt file,

        dir > t.txt

You cannot see anything in the screen, but everything supposed to be displayed saved in t.txt file.
It calls "output redirection".
If you want to print out,
        dir > prn

We can utilize this skill for java with compiled program (e.g., double_data.class).
e.g.,  in cmd windows,
        java  double_data  >  t.txt
